[0042] A magnetic field enhanced induction heating furnace for heating and extracting volatile components of lunar soil provided by an embodiment of the present invention includes a collector 100, a heating shell assembly 200, an annular magnetic conduction assembly 300, and a magnetic induction coil 400. The collector 100 is configured with a bearing cavity 110, and the bearing cavity 110 is configured with air vents penetrating the chamber, and the bearing cavity 110 is used to bear lunar soil 800; the heating shell assembly 200 is configured with a heating cavity 230, and the heating shell assembly 200 is further configured with a ventilation pipe 240 communicating with the heating cavity 230, and the ventilation pipe 240 is used to communicate with a gas analyzer; the annular magnetic conduction assembly 300 is accommodated in the heating cavity 230, and the annular magnetic conduction assembly 300 includes a magnetic conduction sleeve 310 and a magnetic conduction member 320; the magnetic conduction sleeve 310 is a closed structural frame, and the magnetic conduction member 320 is accommodated in the structural frame and connected to the magnetic conduction sleeve 310; the collector 100 is accommodated in the heating cavity 230 and sleeved on the outer periphery of the magnetic conduction member 320; the magnetic induction coil 400 is wound and fixed on the outer periphery of the magnetic conduction member 320 and is spaced from the collector 100; the magnetic induction coil 400 can generate a magnetic field under the action of energization, and the magnetic induction lines of the magnetic field can be constrained by the annular magnetic conduction assembly 300.

[0043] When it is necessary to analyze the volatile components of lunar soil 800, the lunar soil 800 is heated by the magnetic field enhanced induction heating furnace for heating and extracting volatile components of lunar soil provided by the present invention so that the volatile components in the lunar soil 800 can volatilize. At this time, the lunar soil 800 is first borne by the bearing cavity 110 of the collector 100, and the collector 100 is sleeved on the outer periphery of the magnetic conduction member 320. At this time, the magnetic induction coil 400 generates a magnetic field under the action of energization, and the magnetic induction lines of the magnetic field can pass through one end of the magnetic conduction member 320 wound in the magnetic induction coil 400 and be transmitted to the other end of the magnetic conduction member 320 through the magnetic conduction sleeve 310 having a closed structural frame structure. Since the magnetic induction lines of the magnetic field generated by the magnetic induction coil 400 of the magnetic field enhanced induction heating furnace for heating and extracting volatile components of lunar soil can be constrained by the annular magnetic conduction assembly 300, the number of magnetic induction lines passing through the annular magnetic conduction assembly 300 is large, so that the magnetic induction intensity of the annular magnetic conduction assembly 300 is enhanced, and then the induced current generated by the collector 100 sleeved on the outer periphery of the magnetic conduction member 320 is large, and the larger induced current can make the collector 100 heat up faster, so that the heating efficiency of heating the lunar soil 800 is also high, the volatile components in the lunar soil 800 volatilize faster, and then the time required for a single sample detection is shorter, and the time required for the entire research process will also be shorter, and the efficiency is high.

[0044] Specifically, during the heating process of the lunar soil 800 in the bearing cavity 110, the volatile components volatilize and flow into the heating cavity 230 through the air vents, and then flow into the gas analyzer through the ventilation pipe 240 for analysis.

[0045] In one specific embodiment, the magnetic conduction member 320 and the magnetic conduction sleeve 310 are made of an iron-silicon-aluminum alloy, which has a good constraining effect on magnetic induction lines. The collector 100 is made of a stainless steel material, such as a 316 stainless steel plate. Of course, the collector 100 can also be made of a titanium alloy TC4, and no special limitation is made thereto.

[0046] It should be noted that when the magnetic field enhanced induction heating furnace provided by the present invention for heating and extracting volatile components of lunar soil is installed in a lunar soil analysis and detection device and taken to the moon, the volatile components of the lunar soil can be analyzed and studied. Of course, if the lunar soil analysis and detection device equipped with the magnetic field enhanced induction heating furnace provided by the present invention for heating and extracting volatile components of lunar soil is taken to other celestial bodies, the lunar soil 800 on other celestial bodies can also be analyzed and detected, such as Venus, Jupiter, etc., and no limitation is made thereto.

[0047] Please refer to Figure 7 , the magnetic conduction sleeve 310 of the magnetic field enhanced induction heating furnace provided by an embodiment of the present invention for heating and extracting volatile components of lunar soil includes a first sleeve 311 and a second sleeve 312 that are oppositely arranged along the axis; the heating shell assembly 200 includes a first outer shell 210 and a second outer shell 220 that are oppositely arranged along the axis; the first outer shell 210 covers and is connected to the outer periphery of the first sleeve 311, the second outer shell 220 covers and is connected to the outer periphery of the second sleeve 312, the first outer shell 210 can approach or move away from the second outer shell 220, and the first outer shell 210 can be in sealed abutment with the second outer shell 220 so that the heating cavity 230 is a closed cavity.

[0048] When it is necessary to carry the lunar soil 800 in the collector 100 after sampling the lunar soil 800 on a celestial body, at this time, the first outer shell 210 is moved away from the second outer shell 220 so that the collector 100 can be exposed from the heating cavity 230, so that the lunar soil 800 can be poured into the collector 100. After pouring a predetermined weight of lunar soil 800 into the collector 100, the first outer shell 210 is moved closer to the second outer shell 220, and the first outer shell 210 and the second outer shell 220 are in sealed abutment, so that the heating cavity 230 is a closed chamber. Thus, when heating the lunar soil 800 in the collector 100, the volatile components are not easily leaked out from the connection between the first outer shell 210 and the second outer shell 220, and further, the content of the volatile components finally flowing into the gas analyzer is more accurate, and the accuracy of the analysis of the volatile component content of the lunar soil 800 is also higher.

[0049] Please refer to Figure 7, in an embodiment of the present invention, an inner wall of the inner shell of the first outer shell 210 of the magnetic field enhanced induction heating furnace for heating and extracting volatile components from lunar soil is recessed inward along its own thickness direction to form a clamping groove 211; the second outer shell 220 is provided with a clamping arm 221 protruding outward along the axis. When the first outer shell 210 and the second outer shell 220 are in sealed contact, the clamping arm 221 can extend into the clamping groove 211. By providing the clamping groove 211 on the first outer shell 210 and the clamping arm 221 on the second outer shell 220, when the first outer shell 210 and the second outer shell 220 are in contact, the clamping arm 221 can extend into the clamping groove 211, so that the first outer shell 210 can form a wrapped structure around the second outer shell 220. After the first outer shell 210 and the second outer shell 220 are in sealed contact, the sealing performance of the heating chamber 230 is better, and thus the volatile components of the lunar soil 800 are not easily leaked.

[0050] Specifically, the first outer shell 210 is configured with a first chamber, and the second outer shell 220 is configured with a second chamber. When the first outer shell 210 and the second outer shell 220 are in sealed contact, the first chamber and the second chamber jointly enclose to form the heating chamber 230.

[0051] Please refer to Figure 6 and Figure 7 , an embodiment of the present invention provides a magnetic field enhanced induction heating furnace for heating and extracting volatile components from lunar soil, which further includes a sealing ring 700. The sealing ring 700 is installed on the second outer shell 220. When the first outer shell 210 and the second outer shell 220 are in sealed contact, both sides of the sealing ring 700 can respectively abut against the first outer shell 210 and the second outer shell 220. By providing the sealing ring 700, the sealing performance of the first outer shell 210 and the second outer shell 220 is further improved, so that when the volatile components in the lunar soil 800 volatilize, they are not easily leaked from the contact portion between the first outer shell 210 and the second outer shell 220.

[0052] Please refer to Figure 7 , the first sleeve 311 of the magnetic field enhanced induction heating furnace for heating and extracting volatile components from lunar soil provided by an embodiment of the present invention includes a first support rod 3111, a second support rod 3112 and a third support rod 3113; both ends of the second support rod 3112 are respectively connected to the first support rod 3111 and the third support rod 3113, and the first support rod 3111 and the third support rod 3113 are opposite, spaced and parallel. By setting the first sleeve 311 in a way of connecting three support rods, and the first support rod 3111 and the third support rod 3113 are opposite, spaced and parallel, the center of gravity of the entire structure of the first sleeve 311 is in the middle, so that the first outer shell 210 connected thereto is more stable and not easily toppled, and the stability of the entire magnetic field enhanced induction heating furnace for heating and extracting volatile components from lunar soil is higher.

[0053] It should be noted that the first support rod 3111, the second support rod 3112, and the third support rod 3113 can be integrally formed into a first sleeve 311 by casting, or the three support rods can be formed into a first sleeve 311 by welding.

[0054] Please refer to Figure 7 , the second sleeve 312 of the magnetic field enhanced induction heating furnace for heating and extracting volatile components of lunar soil provided by an embodiment of the present invention includes a fourth support rod 3121, a fifth support rod 3122, and a sixth support rod 3123; both ends of the fifth support rod 3122 are respectively connected to the fourth support rod 3121 and the sixth support rod 3123, and the fourth support rod 3121 and the sixth support rod 3123 are opposite, spaced apart, and parallel to each other. By setting the second sleeve 312 in a manner of connecting three support rods, and the fourth support rod 3121 and the sixth support rod 3123 are opposite, spaced apart, and parallel to each other, the center of gravity of the entire structure of the second sleeve 312 is located in the middle, so that the second outer shell 220 connected thereto is relatively stable and not prone to tipping, and the stability of the entire magnetic field enhanced induction heating furnace for heating and extracting volatile components of lunar soil is relatively high.

[0055] It should be noted that the fourth support rod 3121, the fifth support rod 3122, and the sixth support rod 3123 can be integrally formed into a second sleeve 312 by casting, or the three support rods can be formed into a second sleeve 312 by welding.

[0056] Please refer to Figure 7 , the central axes of the first support rod 3111 and the fourth support rod 3121 of the magnetic field enhanced induction heating furnace for heating and extracting volatile components of lunar soil provided by an embodiment of the present invention coincide, and the central axes of the third support rod 3113 and the sixth support rod 3123 coincide. Since the central axes of the first support rod 3111 and the fourth support rod 3121 coincide, and the central axes of the third support rod 3113 and the sixth support rod 3123 coincide, when the first outer shell 210 abuts against the second outer shell 220, the first sleeve 311 and the second sleeve 312 can jointly enclose a rectangular frame structure, which not only makes the stability of the entire magnetic field enhanced induction heating furnace for heating and extracting volatile components of lunar soil relatively high, but also makes the rectangular frame structure more conform to the trajectory of the magnetic induction lines of the magnetic field compared with the closed structure frames of other shapes, so that the magnetic induction lines of the magnetic field generated when the magnetic induction coil 400 is energized can be better constrained; at the same time, the first sleeve 311 and the second sleeve 312 are also easy to process and have high feasibility.

[0057] Please refer to Figure 6 and Figure 7, in an embodiment of the present invention, the magnetic conductive member 320 of the magnetic field enhanced induction heating furnace for heating and extracting volatile components from lunar soil includes a first magnetic conductive rod 321 and a second magnetic conductive rod 322 that are oppositely arranged along the axial direction; one side of the first magnetic conductive rod 321 away from the second magnetic conductive rod 322 is fixedly connected to the first sleeve 311, and one side of the second magnetic conductive rod 322 away from the first magnetic conductive rod 321 is fixedly connected to the second sleeve 312; the magnetic induction coil 400 is wound and fixed around the outer periphery of the first magnetic conductive rod 321, and the collector 100 is sleeved and installed around the outer periphery of the second magnetic conductive rod 322; when the first outer shell 210 is in sealed contact with the second outer shell 220, the first magnetic conductive rod 321 is in contact with the second magnetic conductive rod 322.

[0058] By setting the magnetic conductive member 320 as two opposite magnetic conductive rods, and the two magnetic conductive rods are respectively connected to the first sleeve 311 and the second sleeve 312, so that one of the magnetic conductive rods is connected to the first outer shell 210, and the other magnetic conductive rod is connected to the second outer shell 220. When the first outer shell 210 approaches or moves away from the second outer shell 220, the first magnetic conductive rod 321 can approach or move away from the second magnetic conductive rod 322, and the structure of the entire magnetic field enhanced induction heating furnace for heating and extracting volatile components from lunar soil is relatively simple. At the same time, since the first magnetic conductive rod 321 can be in contact with the second magnetic conductive rod 322 when the first outer shell 210 is in contact with the second outer shell 220, it can effectively reduce the magnetic resistance brought by air during the transmission of magnetic induction lines through the magnetic conductive member 320, thereby increasing the magnetic flux passing through the magnetic conductive member 320 and having a stronger magnetic induction intensity, and finally making the induced current generated by the collector 100 larger.

[0059] In one specific embodiment, the first magnetic conductive rod 321 is fixedly connected to the second support rod 3112, and the second magnetic conductive rod 322 is fixedly connected to the fifth support rod 3122.

[0060] Please refer to Figure 6 and Figure 7 , in an embodiment of the present invention, one of the first magnetic conductive rod 321 and the second magnetic conductive rod 322 of the magnetic field enhanced induction heating furnace for heating and extracting volatile components from lunar soil is configured with a clamping protrusion 3221, and the other is configured with a clamping groove 3211; when the first magnetic conductive rod 321 is in contact with the second magnetic conductive rod 322, the clamping protrusion 3221 is in clamping fit with the clamping groove 3211. By providing a clamping protrusion 3221 on at least one of the first magnetic conductive rod 321 and the second magnetic conductive rod 322, and a clamping groove 3211 on the other, the assembly effect between the two is better.

[0061] Please refer to Figure 6 and Figure 7The magnetic field enhanced induction heating furnace for heating and extracting volatile matter from star soil provided by an embodiment of the present invention further includes a heat insulating sheet 510, which is sleeved on the outer periphery of the magnetic conductive member 320 and is arranged between the collector 100 and the magnetic induction coil 400. By providing the heat insulating sheet 510, when the star soil 800 carried in the collector 100 is heated, the heat generated in the second housing 220 is not easily transmitted to the side of the magnetic induction coil 400, so that the temperature of the magnetic induction coil 400 will not be high, and it is prevented from being damaged due to overheating.

[0062] In one specific embodiment, there are multiple thermal insulation sheets 510, and the multiple thermal insulation sheets 510 are arranged at intervals along the axial direction. Lapping blocks 520 are also arranged between the multiple thermal insulation sheets 510, and the adjacent thermal insulation sheets 510 are connected by the lapping blocks 520, so that the thermal insulation effect between the collector 100 and the magnetic induction coil 400 is better.

[0063] It should be noted that when a heat insulation sheet 510 is provided in the magnetic field enhanced induction heating furnace for heating and extracting volatiles from star soil, since the collector 100 is disposed on the side of the heat insulation sheet 510 away from the magnetic induction coil 400, that is, in the second chamber of the second shell 220, the ventilation pipe 240 is connected to the second chamber at this time, so that after the star soil 800 in the collector 100 is heated, the volatiles evaporate and flow into the second chamber through the ventilation holes, and then flow into the gas analyzer through the ventilation pipe 240 for analysis.

[0064] See also Figure 1 , Figures 3-5 Combined with Figure 6 The magnetic field enhanced induction heating furnace collector 100 for heating and extracting volatile matter from star soil provided in one embodiment of the present invention is configured with a first collection hole 120; the magnetic field enhanced induction heating furnace for heating and extracting volatile matter from star soil also includes a first temperature measuring device 610, the first temperature measuring device 610 is opposite to the first collection hole 120, and the first temperature measuring device 610 is opposite to the cavity wall of the bearing cavity 110 and is arranged at a distance, and the first temperature measuring device 610 is used to measure the temperature of the cavity wall of the bearing cavity 110 close to the magnetic conductive member 320. The first temperature measuring device 610 is used to measure the temperature of the cavity wall of the bearing cavity 110 close to the magnetic conductive member 320, so that the temperature in the collector 100 can be determined, and then the heating temperature of the star soil 800 carried in the bearing cavity 110 can be determined, and the heating temperature of the star soil 800 can be adjusted according to the detection result. In one specific embodiment, the first temperature measuring device 610 is a thermopile; in another specific embodiment, the first temperature measuring device 610 can also be a thermocouple.

[0065] See also Figure 2 , Figure 4 , Figure 5 Combined withFigure 6 The magnetic field enhanced induction heating furnace for heating and extracting volatiles from star soil provided by one embodiment of the present invention further includes a second temperature measuring device 620, which can pass through the collector 100 and extend into the bearing cavity 110 to measure the temperature of the bearing cavity 110. Specifically, the collector 100 is configured with a second collection hole 130, and the second temperature measuring device 620 extends into the bearing cavity 110 through the second collection hole 130. The bearing cavity 110 is measured by the second temperature measuring device 620, and the temperature in the collector 100 is determined by comparing the measurement results of the first temperature measuring device 610 and the second temperature measuring device 620, so that the measured temperature of the collector 100 is more accurate. In one specific embodiment, the temperature in the collector 100 is the average value of the measurement results of the first temperature measuring device 610 and the second temperature measuring device 620. In one specific embodiment, the second temperature measuring device 620 is a thermocouple; in another specific embodiment, the second temperature measuring device 620 is a thermopile.

[0066] In one specific embodiment, the vent holes through the chamber constructed on the bearing chamber 110 are the first collection hole 120 and the second collection hole 130. When the star soil 800 is heated, the volatilized volatiles can flow into the heating chamber 230 through the first collection hole 120 and the second collection hole 130, and finally flow into the gas analyzer for analysis through the vent pipe 240.

[0067] See also Figures 1-5 The magnetic field enhanced induction heating furnace for heating and extracting volatiles from star soil provided by one embodiment of the present invention also includes a third temperature detector 630. The third temperature detector 630 is installed on the outer wall of the heating shell assembly 200 away from the heating chamber 230. The temperature of the outer wall of the heating shell assembly 200 can be measured by the third temperature detector 630, so that the user can know the temperature of the periphery of the magnetic field enhanced induction heating furnace for heating and extracting volatiles from star soil, and then judge whether the magnetic field enhanced induction heating furnace for heating and extracting volatiles from star soil itself affects the use of its peripheral components due to excessive temperature, or causes thermal damage to other peripheral components. In one specific embodiment, the third temperature detector 630 is a thermopile; in another specific embodiment, the third temperature detector 630 can also be a thermocouple.
